I just (2 days ago) had one GPU applied for SEA-SFO-LAX-HNL-LAX-SFO-PDX. Upgrades cleared instantly for ALL but the first (SEA-SFO) leg, due to lack of R space. This was done online using the "Redeem Upgrade" link. Total time on the ground in HNL is +/- 2:30.
So for those saying it's not going to happen -- you're wrong.
Having said that, I don't know how it works if you have an overnight in LAX.
